Modern versions of Linux use a type of Windows file sharing called
"The Common Internet File System" (CIFS). Instead of using
"smbmount", try:
mount -t cifs //1.2.3.4/share
/mnt/somedirectory
For more information about this, in a terminal
you can do:
man mount.cifs
Note that CIFS can't resolve Windows computer names, so you're better off
using their IP addresses.
